Antipov A, Okorokova N, Mordkovich N, Safonova T, Veiko V. Role of phosphate-coordinating arginine residues in the thermal stability of uridine phosphorylase from Shewanella oneidensis MR-1. Biochimie 2024; 225:19-25. [PMID: 38723939 DOI: 10.1016/j.biochi.2024.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/15/2024] [Accepted: 05/06/2024] [Indexed: 05/24/2024]
Abstract
The role of phosphate-coordinating arginine residues in the thermal stability of uridine phosphorylase from Shewanella oneidensis MR-1 was investigated by mutation analysis. Uridine phosphorylase mutant genes were constructed by site-directed mutagenesis. The enzyme mutants were prepared and isolated, and their kinetic parameters were determined. It was shown that all these arginine residues play an important role both in the catalysis and thermal stability. The arginine residues 176 were demonstrated to form a kind of a phosphate pore in the hexameric structure of uridine phosphorylase, and they not only contribute to thermal stabilization of the enzyme but also have a regulatory function. The replacement of arginine 176 with an alanine residue resulted in a significant decrease in the kinetic stability of the enzyme but led to a twofold increase in its specific activity.

Enzymatic Synthesis of 2-Chloropurine Arabinonucleosides with Chiral Amino Acid Amides at the C6 Position and an Evaluation of Antiproliferative Activity In Vitro. Int J Mol Sci 2023; 24:ijms24076223.

Abstract
A number of purine arabinosides containing chiral amino acid amides at the C6 position of the purine were synthesized using a transglycosylation reaction with recombinant E. coli nucleoside phosphorylases. Arsenolysis of 2-chloropurine ribosides with chiral amino acid amides at C6 was used for the enzymatic synthesis, and the reaction equilibrium shifted towards the synthesis of arabinonucleosides. The synthesized nucleosides were shown to be resistant to the action of E. coli adenosine deaminase. The antiproliferative activity of the synthesized nucleosides was studied on human acute myeloid leukemia cell line U937. Among all the compounds, the serine derivative exhibited an activity level (IC50 = 16 μM) close to that of Nelarabine (IC50 = 3 μM) and was evaluated as active.

Rational Mutagenesis in the Lid Domain of Ribokinase from E. coli Results in an Order of Magnitude Increase in Activity towards D-arabinose. Int J Mol Sci 2022; 23:ijms232012540. [PMID: 36293391 PMCID: PMC9604405 DOI: 10.3390/ijms232012540] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 10/12/2022] [Accepted: 10/16/2022] [Indexed: 11/16/2022] Open
Abstract
Development of efficient approaches for the production of medically important nucleosides is a highly relevant challenge for biotechnology. In particular, cascade synthesis of arabinosides would allow relatively easy production of various cytostatic and antiviral drugs. However, the biocatalyst necessary for this approach, ribokinase from Escherichia coli (EcoRK), has a very low activity towards D-arabinose, making the synthesis using the state-of-art native enzyme technologically unfeasible. Here, we report the results of our enzyme design project, dedicated to engineering a mutant form of EcoRK with elevated activity towards arabinose. Analysis of the active site structure has allowed us to hypothesize the reasons behind the low EcoRK activity towards arabinose and select feasible mutations. Enzyme assay and kinetic studies have shown that the A98G mutation has caused a large 15-fold increase in kcat and 1.5-fold decrease in KM for arabinose phosphorylation. As a proof of concept, we have performed the cascade synthesis of 2-chloroadenine arabinoside utilizing the A98G mutant with 10-fold lower amount of enzyme compared to the wild type without any loss of synthesis efficiency. Our results are valuable both for the development of new technologies of synthesis of modified nucleosides and providing insight into the structural reasons behind EcoRK substrate specificity.

Abstract
INTRODUCTION Nucleoside analogues represent a cornerstone of achievement in drug discovery, rising to prominence particularly in the fields of antiviral and anticancer discovery over the last 60 years. Traditionally accessed using chemical synthesis, a paradigm shift to include the use of biocatalytic synthesis is now apparent. AREAS COVERED Herein, the authors discuss the recent advances using this technology to access nucleoside analogues. Two key aspects are covered, the first surrounding methodology concepts, effectively using enzymes to access diverse nucleoside analogue space and also for producing key building blocks. The second focuses on the use of biocatalytic cascades for de novo syntheses of nucleoside analogue drugs. Finally, recent advances in technologies for effecting enzymatic nucleoside synthesis are considered, chiefly immobilization and flow. EXPERT OPINION Enzymatic synthesis of nucleoside analogues is maturing but has yet to usurp chemical synthesis as a first-hand synthesis technology, with scalability and substrate modification primary issues. Moving forward, tandem approaches that harness expertise across molecular microbiology and chemical synthesis will be vital to unlocking the potential of next generation nucleoside analogue drug discovery.

Comparison of Spatial Structures and Packaging of Phosphorybosil Pyrophosphate Synthetase 2 from Thermus thermophilus HB27 in Rhombohedral and Tetragonal Crystals. CRYSTALS 2021.

Abstract
We report the spatial structure of phosphoribosyl pyrophosphate synthetase 2 from the thermophilic bacterium Thermus thermophilus HB27 (TthPRPPS2) obtained at a 1.85 Å resolution using a diffraction set collected from rhombohedral crystals (space group R32-h), grown with lithium sulfate as a precipitant. This crystal structure was compared with the structure of TthPRPPS2, previously obtained at a 2.2 Å resolution using diffraction sets from the tetragonal crystals (space group P41212), grown with ammonium sulfate as a precipitant. The comparison of these structures allows the study of the differences between protein molecules in both crystalline structures, as well as the packaging of enzyme molecules in crystals of both spatial groups. Our results may contribute to the research of the structural basis of catalytic activity and substrate specificity of this enzyme.
